BOILER-TUBE ExT'RAoroR.

Specification of Letters Patent. Patented Application filed April 19, 1916. Seria1 No, 92,2 0G.

and State of"Ind iana, have invented jcertain new and useful Improvem entsin Boiler- Tube Extractors; and 'I do hereby declare the following to be a full, clear, and exact description of the invention,- such as Q will enable others skilled in the art to which it appertains to make and use the'same..

This invention 'relates'to a toolwliich is particularly designed for uncrimping or straightening the ends of boiler tubes, for

facilitating their removal from a boiler, and the primary objeotiof the invention is to provide a tool asspecified, which is extremely simple in construction, and eflicient in operation. g

A further object of this, invention is to provide a tool as specified,which includes a handle bar having a head formed upon one end of the same, which head is shaped for engaging the interior of a boiler flue, and rounded so as to permit of a pivotal movement of the tool without marring or rupturing the interior of the flue, and a crimp engaging and straightening member which is pivotally connected to the handle and is moved into firm engagement with the interior of the crimp of the boiler fine by means of a wedge which is driven into an opening formed in the handle bar and engages the rear edge of the crimp engaging member. a

With the foregoing and other objects in view, this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters designate like and corresponding parts throughout the several views, and in which Figure 1 is a erspective view of the improved boiler tu e extractor.

Fig. 2 is a sectional view through the head of the same having the wedge removed therefrom, and

Fig. 3 is a view similar to Fig. 2 showin the wedge inserted in the opening forme in the handle bar.

Fig. 4 is a View showin e a plication,

of the boiler tube extractor,

Referring inore particularly to theidraw 1ng, l deslgnates the handle or, body barlof the tool as an entirety, which has one portion rounded as shown at 2, for forming a hand grip. The body bani has a head3 formed upon its end oppos te tothe rounded por-. tion', which head is shaped for insertion into the interior of a boiler flufe, and-is provided with a cut out; portion indicated at 4 for pre I venting binding action between the head and theround'ed portion of the flue. I The head3 iscurved, so as to permit of a pivotal or downward movement of the tool without} marring or mutilatingthe, interior, offthej flue, and also to actas a fulcrum for the pivotal movement of, the tool.

h o yj a ill i Prov d a an one ing 5 extending transversely therethrough,

throughwhich the shank 6 of the crimp or bead engaging jaw 7 extends. The head 8 of the head or crimp engaging jaw is curved, and is provided with an inserting edge 9 which is adapted for insertion between the ciiimped or beaded end of a flue and a boiler p ate.

When the tool is initially applied for uncrimping the end of a boiler fiue for facilitating its extraction from the boiler, the head 3 is positioned interiorly of the flue,

and the inserting edge 9 is positioned at the 1 upper edge of the crimp or bead and against the boiler plate. The wedge 10 is then driven into the opening 5 back of the shank 6, which will move theupper end or head 8 of the jaw 7 forwardly and downwardly upon its pivotal pin '11, for forcing it be- The handle 2 is then gripped and the entire tool is moved downwardly which will uncrimp or straighten the beaded or crimped end of the flue for facilitating its removal from aboiler.

In reducing the invention to practice, certain minor features of construction, combination and arrangement of parts may necessitate alterations to which the patentee is entitled provided such alterations are comprehended within the scope of what is claimed.

What is claimed is 1. In a boiler-tube extracting tool, a body bar, one end of said body bar shaped to form a h d gr p, a head form d p n the other vided with an opening extending there through, a boiler tube engaging jaw having a shank, saidshank extending through said opening and being pivotally connected to said body bar, said jaw provided with an inserting edge, and a wedge for driving into said opening agalnst the rear edge of said jaw for forcing said inserting edge between a'boiler tube bead and a boiler plate.

QLIn a boiler tube extracting tool, a body bar having one end rounded to form a handle and the other end shaped for fitting against the interior of a boiler tube to act as a fulcrum for the tool, said body provided with a vertical opening, a aw having a shank, said shank extending through said opening and pivotally connected to said body, and a wedge for insertion into said opening against the rear edge of said jaw for driving the jaw between a boiler head and a tube bead, the forward wall of said recesses limiting the pivotal movement of said jaw by said wedge.

3. In a boiler tubeextractor, a body bar having the-fulcrum head formed upon one end andprovided with'the vertical opening,

Copies of this patent may be obtained for a jaw including a shank, said shank extending through said opening and pivotally connected to said body bar, a head formed upon the upper end of said shank and including a downwardly extending portion having its lower end sharpened transversely to the length of the body for insertion between the head of a boiler tube and a boiler head and means for engagement with said shankfor pivotally moving said jaw to drive said sharpened edge between a tube bead and boiler head, the forward wall of said open ing limiting the pivotal movement of said jaw,

In testimony whereof I aflix by signature in presence of two witnesses.
